Abstract
Ushbu maqolada podshipniklarda yuzaga keladigan kontakt kuchlanishlarni aniqlash usullari hamda ularning iqtisodiy samaradorlikka ta’siri tahlil qilingan. Sharikli va rolikli podshipniklarda kontakt yuzalarida hosil bo‘ladigan kuchlanishlarning paydo bo‘lish mexanizmi va taqsimlanish qonuniyatlari ko‘rib chiqildi. Elastiklik nazariyasiga asoslanib, kontakt kuchlanishlarni hisoblash uchun zarur bo‘lgan asosiy matematik bog‘lanishlar keltirildi.
Bundan tashqari, kontakt kuchlanishlarning qiymati podshipnikning xizmat muddati, ishonchliligi va texnik xizmat xarajatlariga qanday ta’sir ko‘rsatishi iqtisodiy nuqtai nazardan baholandi. Tahlillar shuni ko‘rsatadiki, optimal konstruktiv parametrlarni tanlash orqali kontakt kuchlanishlarni kamaytirish nafaqat texnik ishonchlilikni oshiradi, balki ekspluatatsiya xarajatlarini qisqartirish orqali umumiy iqtisodiy samaradorlikni ham ta’minlaydi. Olingan natijalar sanoat korxonalarida podshipniklarni tanlash va ulardan foydalanishda muhim ilmiy-amaliy ahamiyatga ega.
